To solve the problem of off-tracking from line of light bus,a domestic light bus is taken as the study object.The components are linked rigidly,the body is considered as a simple mass and a 12 Degree of Freedom(DOF) dynamical simulation model is set up based on MSC Adams package Aview in which tyre model and road model are combined.The comparison of real vehicle test and simulation shows that the model is more valid and effective.The simulation also shows the relationship of off-tracking from line and position parameters of front tires and provides the basis and corresponding countermeasure for vehicle to find the key factors and solutions on off-tracking from line quickly.
